PRELIMINARY
CGH40025F
25 W, RF Power GaN HEMT
Cree’s CGH40025 is an unmatched, gallium nitride (GaN) high
electron mobility transistor (HEMT). The CGH40025, operating
from a 28 volt rail, offers a general purpose, broadband solution
to a variety of RF and microwave applications. GaN HEMTs offer
high efficiency, high gain and wide bandwidth capabilities making
www.DataSheetth4Ue.cCoGmH40025 ideal for linear and compressed amplifier circuits.
The transistor is available in a screw-down, flange package.
